AI Security Review
scanned 6d ago · by lpm-firewall-aiThe manifest has no install hook, and the flagged editor configuration and persistence artifacts are created through explicit setup or install commands. The Antigravity adapter does not load its launchd watcher, and network requests target the package’s configured Agnoclast service.
Static reason
No blocking static signals were detected.
Trigger
The MCP server runs when launched by an editor; configuration and Antigravity artifacts are written only when setup or install is invoked.
Impact
Expected service access and opt-in editor configuration; no automatic exfiltration, persistence activation, or unrelated account action identified.
Mechanism
The client sends authenticated API requests to its configured Agnoclast service. The Antigravity setup writes a watcher script and plist but does not activate the watcher.
AI rationale
The manifest has no install hook, and the flagged editor configuration and persistence artifacts are created through explicit setup or install commands. The Antigravity adapter does not load its launchd watcher, and network requests target the package’s configured Agnoclast service.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest declares no install lifecycle hook; its scripts are release, promote and rollback commands.
- Editor configuration writes are reached through explicit setup or install CLI commands.
- The Antigravity adapter writes a script and launchd plist but does not load the watcher.
- The client’s default API base is the package’s Agnoclast service at https://agnoclast.com.
